Akie Iwai was right back on top of the leaderboard in the CPKC Women's Open on Thursday, four days after her breakthrough victory in the Portland Classic.

Iwai's back-to-back birdies to finish her round helped her leap over a cluster of players that held the lead for most of the day. Canadian amateur Aphrodite Deng, Mexico's Gaby Lopez, and Megan Khang shared the clubhouse lead at 5 under after the morning wave.
